Mr. Wutakara is a very kind, gentle and humble person living with their two cats. His hidden fortress is a gem. Don't worry if you're not comfortable with cats since you won't see them around unless you ask him where can you see them.
He prepared an amazing breakfast daily at different times (based on whatever time we told him). His punctuality is a spot on. If you say 10 AM you'll have the breakfast on the table exactly at 10; neither a minute before nor a minute later.
He is a local and can guide you on places to visit and things to do in Bangkok. The place has a local market and a shopping center just on the main road. These are great places to shop and also try some street food.
Lastly, he has a car that he doesn't drive anymore, but if you're doing a Taxi through Grab, please ask him to help you explore the city in his car. You'll not only save time but would also have someone who can speak the local language and be more secure with him. Please pay him what you'll pay in Grab, and you'll have an amazing experience. Unfortunately, uncle never told us about the car till the very last day when only when we had a lot of luggage and wanted to reach the airport in the night.
Overall, this place is a hidden gem. It is a little far away from the touristy places and would not only provide you a place to see some authentic culture, but a local like uncle can be a blessing. He also likes company of others and I'm sure you'll also love his company while exploring with the city with him.
